To all whom it may concern:

Be it known that I, FRANK SCHUH, a citi-` zen of the United States, and a resident of Trenton, in the county of Mercer and State of New Jersey, have invented a new and Improved Tater-Closet, of which the following is a full', clear, and exact description.

The invention relates to water closets using' compressed air for the forcible ejection of the water from a tank into the bowl.

The object of the invention is to provide a new and improved water closet arranged to occupy a small amount'of space, to insure eilicient and thorough flushing of the bowl, and to allow use of the water closet with a high or low pressure source of Water supply. Another object is to facilitate the siphoning;r action of the. bowl. and to provide n rc-` licf valve in the water tank to insure completedischarge of the last ortion of the water in the lower portion ci) the tank'and' to conduct such water into the bowl toy raise the level of the water therein.

A further object is to provide a Water closet which can be set on a floor or attached to 'a wall a distance above the` floor.

Inorder to accomplish the desired result use is made of a bowl having a liushing rim, a closed water tank, a compressed air chamben below the said water tank, a connection between the said water tank and the Said air chamber, and a valve mechanism connect with a source of water suppl and adaptedl to connect the said Water tan with the water supply, and to connect the water tank with the flushing rim.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, -in which similar ciaractcrs of reference indicate corresponding parts in all the views.

Figure 1 is a sectional sidee'levation of the water closet with' the seat in closed posi tion and the water fillingfthe Water tank;

Fig. 2 is an enlarged sectional side elevation of part of the same with the seat raisedl and the Water flowing from the water tank into the bowl;

Fi 3 is an enlarged cross section of the, air chamber, part of the Water tank and the line 3-#3 of Fig. 1;

Fig. 4 is an enlarged sectional plan vievn` lof the valve mechanlsm on the line 4-4 of igf is an enlarged sectional viewl pf thel valve mechanism, the bowl andthe inlet chamber for the bowl, the section being on the line 5-5 of Fig. 2; and n Flg. 6 is a cross section of the water closet on the line. 6-6 of Fig. l;

The bowl Ak of the water closetis rovlded with the usual flushing rim B an the bottom of the bowl A is connected by a Water seal or siphon C with the reduced outlet D arranged in the base or bottom E. T'he leg C of the Siphon C is inclined upwardly and rearwardly and the leg C2 ol. the si hon is of flat oval sha )e at the dam or mout i C and ris enlarged flrom the dam or mouth downward `to the reduced outlet D. Owin to the narrow dam or mouth, a comparativcly little amount of Water is required to start the Siphon and as the water after leaving the dam or mouth C can readily spread a quick and posit-ive siphoning action is had. In order to render the siphoningi; action comparatively noiscless, a delecting rib C* is arranged inthe left wall of the leg C2 to deflect the down rushing wntcr to tbe right into the enlarged lower portion of the leg C2 and which lower portion is connected at its left with the outlet D. Thewater is thus conducted in a lateral direction to the outlet D instead of dropping directly down Sli into it from the dam or mouth C3. The sev'- eral parts mentioned are integrally con nected with a Water tank F und with a com# pressed air chamber (in arranged below the water tank F, the latter and the said air chamber G being located in the rear of the bowl A, asplainly indicated in 1 and 2. The rear wall of the integral single-piece structure thus far described is disposed vertically to allow of snugly setting the structure against the wall of a buildingor fas toning it to such wall, if desired, with the bottom E above the door. The said rear Wall is provided with a manhole F' to permit of obtaining access to the, interior of the tank F whenever it is desired to do so.

5 The bowl A is provided with a seatfH hingediat H to the front of the `upprpor tion of the water tank F, and the said seat H, as shown, controls a valve mechanism I, whi'ch latter, however, may-be actuated by hand and located within reach of the' user. -The valve mechanism I is arranged in an inlet `chamber J preferably `located between the back of the bowl A and the lewe `portion of the water tankiF'aud. in i Awith the Sommand the said-lmet champ" u into t J is connected at its upper portion with the flushing rim B to supply the latter with water, as hereinafter more fully ex iluined. The valve mechanism I is connectedl witha water supply pipe K and controls the inflow of the water from the supply pipe K into the water tank F, and it also controls the flow of water from the tank F to the inlet chamber J of the flushing rim B. An air pipe L connects the upper portion of the Water tank F with the compressed air chamber G so that when the tank F fills with Water the air in the tank F is forced by way of the pipefinto the chamber G and compressed therein.

The valve mechanism-1 is constructed as follows:

Within the inlet chamber J is arranged a' vertically disposed tubular casing N, the lower end of which extends through the bottom of the chamber J into the lower portion .of the water tank F, and on thc said lower end of the casing N is secured a cap O terminating in a nipple O coupled to the water supply pipe K. The bottom of the casing N is provided with an inlet port I opening into the cap O, and the said port P is controlledby a valve Q held on the lower end of a valvestem Q extending centrally in the casing N. The lower portion of the casing N'and the cap O are provided at the sides with registering inlet and outlet -ports P (see Fig. 4) which connect the interior of the lower end of the casing N with the interior of the water tank F. Ail outlet port P2 is arranged in the side of the casing N a distance above the ports P', and this outlet port P2 connects the interior of the lower portion of the casing N with.the inlet chamber J. On the valve stem Q' is secured a iston valve Q2 fitting the lower portion o the casin N and controlling the port P2. The va ves Q and Q2 are so arran ed that when, the

valve 'Qcloses the port 2, as shownin Fig.`V

17 then thevalve Q is in open position relal tive to the port Pto allow the water to flow through the supply pipe K and ports P, P- e tank F to fill the latter. When the vulves Q and Q2 are,in the positionishovjn in Figlf, thefvalve Q2 is above the port 2 and 'e latter i's open While the valve Q closes the port P, an thus shuts o the water flowing from the supply pipe into the tank F. The water in the tank F now flows by Way of the ports P', P2 into the inlet chamber J topass to the flushing' rim to flush the bowl A. Within a. horizontal artition N on which rests the lower end o a'spr: g R pressing with its upper endigainst a' collar Q2 fixed te the stem Qea rying the valve Q and Q2. The upper end'Q ofthe valve stem Q slidingly engages'a top cpp N2 of the casing N, and

tne upper surface of the end Q is engaA ed by a all S held in a bearing S' attache to the under side of the seat H at the rear portion thereof. Normally the spring R holds the vulves Q and Q2 in uppermost position, us shown in Fi f. 2, and at the same time holds the scat 1^ raised, and when the seat is occupied by a person and swung downward into the position shown in Fig. l then the stem Q is pressed downward against the'tension of the spring It and the valves Q and Q2 are moved into the position shown in Fig. 1. As soon as the occupant leaves the seat H the latter swings back into the uppermost position by the action of the spring R pressin Vthe valve stem Q so that the valves Q-an( Q2 return to normal position, as shown in Fig. 2.

From the bottom ot' the inlet chamber J leads a draina e channel J into the bowl A to completely f rain the water out of the said chamber J. The chamber J is also' connected at its bottom by a chan..el J 2 with the bottom of the water seal C so that a portion of the water Vpassing into the inlet chamber J Hows dwn the channel`J2 and into the water seal C to dislodge any sediment that may be in the bottom of the said seal. By reference to Fi 1 it will be seen that the outlet portion o? the channel J 2 is in an upward and rearward direction so as to force the water upwardly and rearwardly in the seal C.

The water supply pipe K is made in sections connected with each other by a coupling K attached to one of the sides of the tank F (see Fig. 3) and the outer section of the supply pipe K connects with a water ma'in in the usual manner.

The casing N is providedwith an annular seat N5 immediately below the port P2 so that when the valve Q2 moves into lowermost position it seats itself on the said seat to tightly shut offthe water t/o the port P2. i

' nular flange N seated on.aJ gasket T held in an annular rabbet or recess J s formed in the top of the chamber J. A gsket T abuts a einst the under side of the bottom of the c amber J and this gasket is engaged by a flan e O2 formed on the cap O`so that when the atter'is screwed up on the casing N it draws the flange N* in firm Contact with'the gasket T and' the Bange 02 moves in firm contact with the asket T so that the casing N is securely hel in position in the chamber J and leakage is prevented at the upper and lower joints of the casing N with the topA and bottom of the chamber J. v

In order to insure a proper filling of the water tank F from the lower portion of the valve chamber J, use is made of a safety o r drainage valve V arranged in the wall of the draina e channel J2 and havin a float V exten ing in the water tank F. he Heat V closics the valve V as soon as the water level in the tank F reaches a predetermined height, and hence ,the Water is not liable to overflow into the air pipe L. lVhcn the water is drawn out of the tank F to flush the bowl A the valve V opens by the downward swinging of the ioat V and the tank F is consequently drained of practically its whole amount of Water by way of the drainage channel J z. The water passin from the tank F into the bowl A b way o the channel J raises the level of t e water in the bowl to the overflow point at the mouth of the siphon.

A. plug W is arranged in one side of the compressed air chamber G to drain the latter of any moisture that may have accumulated therein.

Normally the Water tank F is practically empty as the valve mechanism I is then in the position shown in Fig. 2 with the valve Q in closed position and the valve Q2 in open position, as previously explained, to

allow water to How from the tank F by Way ot' the'ports P', P2 into the inlet chambe'rJ from which the water passes into the bowl, as above set forth. V-VhenI the seat H is occupied and consequently swung' downward then the valves Q and Q2 moveV into the position shown in Fig. 1 whereby the port P2 is closed while the port P is opened to allow the water to How. from the supply pipe K by wey of thefporte P and P into the tank F to fill the same. As the water rises in the tank F theair in the top thereof is forced through the pipeL into the com pressed air chamber (i and compressed therein. W'hcn the said seat H is released and the parts returned to normal position as shown in Fig. 2 then the Water flows out of the tank l into the bowl as previously explained. with thc aidy of the compressed air, so that afvery eiiicient and thorough flushing o'f ,the bowl takes place as the Water is under pressure during the 'outtiow from lhc tank'F.

It will be noticed that by making the bowl A, the siphon C, the compressed air chamber (i, thc valve chamber J and the tank F integral, a very simple structure is .obtained, completely free 'of joints liable to leak. By locating the compressed air chamber (i .1n the lower portion of the structure the height ot thc structure is greatly reduced so that the structure takes comf 2; xA water closet, comprising a bowl having a flushing rim, a closed water tank, a compressed air chamber below the said water tank, a connection between the top of thel said Water tank and the said air chamber, and a spring-pressed valve mechanism hav ing a supply port connected with a source of Water supply and having ports, of which one is an open inlet and outlet port and connects with the said Water tank, and the other is an outlet ort and connects with the {lushing rim o the bowl, the said valve mechanism havin two valves, of which one controls the said supply port and the other the said outlet port.' l
